INTRODUCTION
Congratulations! You have purchased one of the highest-quality water softener/conditioner systems
available today. Your new water softener/conditioner is very efficient in its salt and water usage. The
system is completely automatic and will contribute to better and longer service of all your water-using
appliances. There is very little maintenance required for a water softener/conditioner, and it can give you
many years of trouble-free use. This system has been engineered with the finest-quality components and
materials. You’ll soon be enjoying better water quality and the personal benefits that come from soft/
conditioned water use.
IMPORTANT:ONLY USE ON POTABLE WATER SUPPLIES
Special pre-treatment may be required for well water applications.
Read entire manual before attempting installation or routine service.
Obtain all materials and tools needed for installation before starting.
System and installation must be in compliance with state and local
laws and regulation.
Benefits of Soft/Conditioned Water
1. Save up to 30% of the cost of hot water heating.
2. Reduce dishwashing detergent use up to 75%. See dishwasher owner’s manual for proper amount of
soap at “0” softness.
3. Reduce use of all soaps and cleaning products up to 75%. You may be able to use less shampoo,
conditioners and skin lotions.
4. Reduce laundry soap use up to 75%. Typically, a one-quarter cup to one-half cup of standard laundry
detergent is recommended.
5. Reduced cleaning time and effort. Many people report that their cleaning time is cut in half.
6. The silky-smooth feeling you may experience while rinsing the soap off your skin during a shower is
your natural body oils. Soap actually rinses off much faster with soft/conditioned water, but you may
not feel like the soap is rinsed off because of this slick feeling. You will find that if you shower in hard
water again, it will feel sticky and unclean. Enjoy the fresh, new showering experience; and
remember, you don’t need as much soap now!
7. There are many other benefits of soft/conditioned water that you can now start to enjoy. Studies have
indicated that savings from a softener/conditioner can easily range from $10.00 to $30.00 per month.
Start to experience the benefits of soft/conditioned water now! We hope you enjoy!

INSTALLATION INSPECTION
IS YOUR HOME PRE-PLUMBED?
Your home is pre-plumbed for a water softener/
conditioner if you have a loop in the garage or
laundry room. Typically, there will be 110 volt
outlet within 6 feet of the loop and a 1/2” drain line
stubbed out of the wall. If your home is pre-
plumbed, skip now to Step 1 of Installation
Procedures.
CAUTION: Before starting up system, check water
softener drain line to insure that it will drain
properly.
IF YOUR HOME IS NOT PRE-PLUMBED
If your home is not pre-plumbed for a water softener, then we recommend calling for professional
installation. If you are attempting to install the system yourself, you must determine where to locate the
water softening/conditioning system.
The best location depends on several questions:
1. How will you get the water from the water main to the water softener/conditioner?
2. Where will you run the drain line/waste tube? (see illustration on page 5)
3. Where is a 110V outlet within 6 feet of the softener?
Optional: Run a longer wire to most any 110V outlet.
4. Do you need to run a hard-water line to your outside hose bibs, pool fillers or
irrigation system?
5. Where can the water softener sit on a firm, fairly level concrete floor or slab?
Determine the location of your water softener/conditioner, taking into account the above factors, and
determine what materials and tools will be needed for installation. You are now ready to move on to Step 1
of the installation procedures.
INSTALLATION PROCEDURES
Form KPWS030905 Page 5 of 25

WARNING: Do not attempt to remove the red locking bar (KS5 & KS10 only). The locking
bar is for service only and should only be removed by a trained softener technician.
NOTE: The Air-Check sight glass will NOT have a rubber ball in it. The air-check
on Krystal Pure™ softeners is located in the brine well in the brine tank.
STEP 1 – CONNECT TO WATER SUPPLY
A. Shut off the main water supply to the house. Open the hose bib to relieve pressure and drain out
water. Close the hose bib. Place a bucket or the softener brine tank under the softener loop to
catch the excess water that will spill out when you cut the pipe. Cut the plumbing loop off.
Determine the inlet side of the loop by turning the main water on very slightly until water comes
out of one of the sides of the loop. This is the inlet supply. Warning: You must connect the
incoming side of the softener/conditioner to the inlet supply from the loop. Failure to connect
with the proper directional flow can damage the water softener/conditioner and your household
plumbing.
B. Prepare Source-Select bypass valve or yoke for piping connections.
1. KS10 Source-Select bypass valve connection:
a. Apply O-rings (3-required and included) to tank meter adapter. Lubricate with silicone
(provided).
b. Slip bypass valve into position over O-rings.
c. Connect bypass valve to meter adapter using (4) nuts and bolts (provided).
d. Install drain hose barb. Use Teflon tape on threads. Hose barb can point up or down.
e. Insert tailpieces through union nuts.
f. Attach tailpieces by soldering to the inlet and outlet of the plumbing loop.
g. Place rubber gaskets into the union nuts and thread onto the bypass valve body. It is
not necessary to use lubricant or sealant on rubber gasket or union nuts.
h. Place Source-Select valve into the bypass position by rotating the handles so they are
both perpendicular to the flow path of the inlet and outlet water stream.
2. KS15HE and KS64HE (High-Flow) Source-Select bypass valve connection:
a. Install drain hose barb before attaching Source-Select bypass valve. Use Teflon tape on
threads.
b. Insert the rubber gaskets into the union nuts on the Source-Select bypass valve.
c. Thread the bypass onto the valve control body, hand-tightening both union nuts. It is not
necessary to use lubricant or sealant on rubber gasket or union nuts.
d. Insert tailpieces through union nuts.
e. Attach tailpieces by soldering to the inlet and outlet of the plumbing loop.
f. Place rubber gaskets into the union nuts and thread onto the bypass valve body. It is
not necessary to use lubricant or sealant on rubber gasket or union nuts.
g. Place Source-Select valve into the bypass position by rotating the handles so they are
both perpendicular to the flow path of the inlet and outlet water stream.
STEP 2 – CONNECT TO DRAIN
Typical drain line runs to a floor drain, washing machine drain, sanitary sewer line with a p-trap, a sink
drain or a sump. CAUTION: Check with all local plumbing codes to insure proper installation in
your area. An air-gap may be required. Be sure to install proper drain line size (see specifications or
step 2B for sizing).
A. Slide a ½” I.D. tube onto hose barb located on the back of the valve control body, (you may want
to secure tube with a hose clamp, (not provided)). Connect the tubing to the drain stub out
provided with your pre-plumb loop. Some pre-plumbs may provide an ABS drainpipe to run drain
line to. CAUTION: Be sure drain line discharges properly into a drain to prevent flooding.
Form KPWS030905 Page 6 of 25

B. If the following conditions exist, it is recommended to increase the drain line tubing from ½” to
¾” I.D.
1. Drain line run is over 20’.
2. Drain line vertical run is over 10 feet high with incoming water supply pressure of 60 psi.
(You can increase or decrease height of run 2 feet per 10 psi. variations in either direction, i.e.
12 feet vertical run with 70 psi. or 8 feet vertical run with 50 psi.).
3. Backwash rates exceed 5 gpm (see specifications sheet).
STEP 3 – CONNECT BRINE LINE
A. Connect the 3/8” black brine line to the valve control using the fitting provided. The connection
on the KS15HE is located on the right side of the valve just at the bottom and behind the control.
The connection on the KS5 and KS10 is located on the clear plastic site glass. Connect the other
end of the 3/8” black line to the fitting on top of the brine float located at the top of the brine well
inside the brine tank. The lid of the brine well can be removed by pulling it up. Be sure all
fittings and connections are tight. See page 28.
STEP 4 – START UP THE SYSTEM
KS10 start up:
Note: The following steps will require turning the
indicator knob (figure 1) to various positions.
Push the indicator knob in while manually rotating
the camshaft by, located behind the controller, by hand

points to the desired position.
1. Remove valve cover by releasing the
plastic clip from the back and lifting
the cover up and forward.
2. Rotate indicator knob to the BACKWASH
position (COUNTERCLOCKWISE).
3. Fill the softener/conditioner tank with water.
a. With house water supply off, open
the Source Select bypass valve.
b. Open water supply valve very slowly
to approximately ¼open position.
4. When all of the air has been purged from
the tank (water begins to flow steadily from
the drain), open the main water supply all
the way. Allow water to run to drain until clear.
5. Turn off water supply and let the unit stand for about five minutes
to allow all trapped air to escape from the tank.
6. Add the initial amount of water to the brine tank manually with a bucket or a hose. Add
approximately 4 gallons of water to the brine tank.
7. Slowly turn the water supply valve completely open. Place the conditioner into operation by
turning the indicator knob COUNTERCLOCKWISE to the BRINE/SLOW RINSE position.
8. With conditioner in this position, observe the water level in the brine tank for several minutes to
check that the level is going down. If water level does not recede, then make sure the brine line
fittings are tight and no air can leak into connections.
9. Advance the indicator knob to the FAST RINSE/REFILL position. Let conditioner run in this
position for a minute or so.
10. Advance the indicator knob to just past the FAST RINSE/REFILL position but NOT all the way
to the CONDITIONED WATER position. Run water from a nearby faucet until the water is
clear. Proceed to STEP 5-CONNECT ELECTRICAL.
KS15HE and KS64HE Start up:

approximately 3 gallons of water to the brine
tank.
7. Slowly turn the water supply valve completely
open. Place the conditioner into operation by
slowly turning the cycle indicator COUNTER-
CLOCKWISE to the BRINE/SLOW RINSE
position.
8. With conditioner in this position, observe the
water level in the brine tank for several minutes
to check that the level is going down. If water
level does not recede, then make sure the brine
line fittings are tight and no air can leak into the fitting connections.
9. Advance the cycle indicator to the FAST RINSE position.
Let conditioner run in this position for a minute or so.
10. Advance the cycle indicator to the REFILL position. Hold this position until water starts
to flow through the brine line into the brine tank.
11. Advance the cycle indicator COUNTERCLOCKWISE to the REGENERATION COMPLETE
position and run water from a nearby faucet until the water is clear. Proceed to STEP 5-

housing (see figure 1).
STEP 6 – PROGRAM THE VALVE CONTROL
KS10 programming:
1. Time of Day Setting
Open the access door to access the jumper settings. The jumper should be on the TIME jumper.
Set the time of day to the nearest hour by pressing the black TIME SET button. PM hours are
indicated by a light next to the letters PM on the display window.
Note: The unit is factory-set to regenerate at 2:00a.m. If you prefer to have the unit regenerate at
an earlier or later time, simply set the current time of day accordingly (e.g., to have the unit
regenerate at 4:00a.m. – two hours later - set the clock two hours earlier than the actual time of
day. If it is actually 2:00 p.m., set the time to 12:00 p.m.).
Note: Make sure the Timer Locking Pin is always in the horizontal position during operation.
2. Hardness Setting
Form KPWS030905 Page 8 of 25

Move the jumper to the pins next to the word HARDNESS. Press the black TIME SET button
until the hardness of the incoming water supply is displayed. Note: The factory default is 18 GPG
(Grains Per Gallon). It is a good idea to set your hardness a few grains higher than your actual
hardness because hardness can vary throughout the year. Check with your local water supply
company or municipality to find out the hardness in your area.
3. Capacity Setting
It is NOT necessary to change the capacity setting on your softener/conditioner. It is set at
the factory and determined by the size of the system and the amount of salt used to regenerate the
media bed.
Note: The factory has set the conditioner for the proper Capacity Setting based upon the amount
of Salt used to regenerate the media bed. The settings are designed for optimum efficiencies and
do not need to be changed.
Note: If Potassium is used to regenerate the conditioner. It is recommended to increase the
salt dosage by 3 more pounds. Also, keep the level of potassium low in the brine tank to
prevent bridging. To adjust the salt dosage, locate the salt dosage setting on the right side of the
valve control, insert a small screwdriver into the white indicator knob and move pointer to proper
salt setting.
Note: Put the jumper back on the TIME pins. The jumper must not be left on any pins other
than the top pins next to the word TIME.
4. Calendar Override (Optional)
The factory setting is 15 days. If you would like a different calendar override or none at all,
follow the steps below.
a. Disconnect power.
b. Place jumper on Pin A and reconnect power.
c. Move jumper to Pin B.
d. Press the TIME SET button and hold down. The numbers will scroll from 0 to 15 days.
Release the button when number of days desired for the calendar override appears.
e. Disconnect power.
f. Place jumper back on TIME pins and reconnect power.
5. Manual Regeneration/ Extra Cycle
In the case of power failure, the control can be manually regenerated. Depress the indicator
knob and turn the camshaft to the proper cycle. The following cycle times should be used for
proper regeneration:
BACKWASH – 14 minutes.
BRINE/SLOW RINSE – 52 minutes.
FAST RINSE/ REFILL – 10 minutes.
Return indicator knob to the CONDITIONED WATER position.
For an Extra Cycle, simply push in the indicator knob. It will take a few minutes for regeneration
to start. A normal regeneration will take approximately two hours.
KS15HE and KS64HE Programming:
1. Time of Day Setting
Press the SET button. The display will show the Time of Day with the minutes digit blinking.
The number that is flashing is the number you can change. If you want to change this number,
press the up arrow button to increase the number or the down arrow button to decrease the number.
To accept the number, press the left arrow button to move to the next number. Continue changing
numbers until you have set the current time of day. Press the SET button to enter the value.
2. Time of Regeneration Setting
The next value displayed is the Time of Regeneration. It is set at the factory for 2:00 a.m. If this
is not acceptable, press the SET button and change the time setting the same way the Time of Day
was set. Press the SET button to enter the time.
Form KPWS030905 Page 9 of 25

3. Hardness Setting
The next setting is the amount of water hardness in the incoming water supply expressed in grains
per gallon. The factory default value is set at 18. Check with your local water supplier for the
actual level of hardness for your area. It is recommended to add 3 to the actual value due to
varying levels of water hardness throughout the year. Press the SET button to change the number.
Press the SET button again to enter the value.
4. Salt Amount and Capacity Setting
It is NOT necessary to change the salt amount or capacity setting on your softener/
conditioner. It is set at the factory and determined by the size of the system and the amount of
salt used to regenerate the media bed. The method for changing the settings is the same as for the
previous settings.
Note: The factory has set the conditioner for the proper Capacity Setting based upon the amount
of Salt used to regenerate the media bed. The settings are designed for optimum efficiencies and
do not need to be changed.
Note: If Potassium is used to regenerate the conditioner. It is recommended to increase the
salt dosage by 3 more pounds. Also, keep the level of potassium low in the brine tank to
prevent bridging.
5. Manual Regeneration/ Extra Cycle
In the case of power failure, the control can be manually regenerated. Remove the cover and
turn the camshaft by hand COUNTERCLOCKWISE to each position according to the cycle
indicator. The following cycle times should be used for proper regeneration:
BACKWASH – 4 minutes.
BRINE/SLOW RINSE – 50 minutes.
FAST RINSE/ REFILL – 3 minutes.
Return cycle indicator to the REGENERATION COMPLETE position.
For an Extra Cycle, simply push in the REGEN button. This button is located on the front of the
control. It will take a few minutes for regeneration to start. A normal regeneration will take
approximately two hours.
Factory Default Settings
The KS5, KS10, and KS15HE default settings are as follows:
Model Hardness Capacity Salt Calendar Override
(grains/gallon) (kilo grains) (pounds) (days)
KS10 18 26 6.2 15
KS15HE 18 26.2 5.2 (using h injector) 15
KS64HE 18 43 9.0 (using h injector) 15
USE AND CARE
A. Type of System
Your water softener is a fully automatic Demand Initiated, metered system. This means the
softener meters, or keeps track of, the water used in the home. It uses this information to
determine when to perform the regeneration, or cleaning cycle. The control of the softening
process automatically adjusts to your water use. For example, if you have company and your
water use increases substantially, the softener will adjust to insure you don’t run out of soft water.
If you go away for a time and are not using any water in the home, the softener will adjust again
and not perform a regeneration cycle thereby saving salt and water.
B. Type of Salt
Basically, salt is salt. However, some makes of salt contain more dirt in the bag than others. We
recommend Morton™ or Diamond Crystal™ salt pellets, but any type will work. Salt is readily
available at Lowes.
C. Type of Potassium
Potassium can also be used in the water softener. When Potassium is used however, the softener
control valve will need to be adjusted. Add 3 lbs to the salt amount setting i.e. salt amount = 6 lbs,
